The Coenzyme Q10 （CoQ10） BioAssay ELISA Kit is a quantitative competitive assay for the detection of CoQ10 in human serum，plasma，tissue homogenates and other biological fluids.Detection Range：0.781-50ng/mlSensitivity：<0.469ng/mlPrecision：Intra-assay CV： <8%Inter-assay CV： <10%Assay Principle：This ELISA kit employs the quantitative competitive enzyme-linked immunoassay technique，utilizing a microtiter plate provided in this kit has been pre-coated with CoQ10. Standards and samples are added to the appropriate microtiter plate wells followed by a biotin-conjugated antibody specific to CoQ10. Streptavidin conjugated to Horseradish Peroxidase （HRP） is added to each microplate well and incubated. After TMB substrate solution is added，only those wells that contain CoQ10，Biotin-conjugated antibody and enzyme-conjugated Streptavidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulfuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of CoQ10 in the sample is then determined by comparing the O.D. of the sample to the standard curve.Kit Components：*369832A： Microtiter Strips，1x96 wells （8x12 wells）.*369832B： Standard，2x1 vials369832C： Sample/Standard Dilution Buffer，1x20ml369832D： Antibody （Biotin） （Concentrated），1x60ul369832E： Antibody Dilution Buffer，1x10ml369832F： Streptavidin （HRP） （SABC），1x120ul369832G： SABC Dilution Buffer，1x10ml369832H： TMB Substrate，1x10ml369832J： Stop Solution，1x10ml369832K： Wash Buffer，25X，1x30mlStorage and Stability：Store unopened *369832A at 4ºC; store at -20ºC once opened. Store unopened *369832B at 4°C; once reconstituted，store at 4°C for up to 12 hours or at -20°C for up to 48 hours. Store other components at 4°C. Kit is stable for 6 months after receipt. For maximum recovery of product，centrifuge the original vials after thawing and prior to removing the cap.Assay Summary：1. Wash plate 2 times before adding standards and samples to wells.2.
